The Physics Frontiers podcast explores the latest findings, theories, and research in the field of physics. The show features experts discussing emerging and disruptive developments.

Host Jim Rantschler is a physics professor at Texas A&M University Galveston. He worked for the National Institute of Standards and Technology. Rantschler was also a senior principal engineer at Western Digital. Randy Morrison was his cohost from 2016 until he died in 2022. Morrison was a sculptor, art director, and experimental physicist. He's known for the exquisite parade floats he designed for New Orleans and Disney World.

In the podcast's first episode, Rantschler and Morrison discuss four-vector potential (G4v). Morrison says he'd been searching for this idea since he was 10. Carver Mead, a professor emeritus at the California Institute of Technology, proposed G4v. It is an alternative theory to gravitation. Mead calls his approach Collective Electrodynamics. Its expression is in the language of engineering and quantum theory.

Albert Einstein used tensor calculus equations to formulate his general theory of relativity. The hosts agree that G4v could be a more intuitive way to make predictions. Mead studied Einstein's papers from 1911 and 1912. He was able to complete some formulas Einstein was working on before his death. Podcast listeners learn Mead's findings, including a new fact about the speed of light.

David Wolpert visits Physics Frontiers in one episode. He is a researcher at the Santa Fe Institute who studies game theory, AI, and thermodynamics. At the beginning of the 20th century, three fields were gaining momentum. Quantum mechanics, relativity, and statistical mechanics were all experiencing significant developments. Statistical mechanics is the most useful and prolific, but the least talked about. He reveals why topics like equilibrium and statistical physics are worthy of more discussion. He says it's easy to see how things move on the macroscale. The smaller a system is, the higher the probability is for entropy to change.

The Physics Frontiers podcast shares findings like these. They may change everything from encryption to computation.
